I'm intrigued. Was this done to establish evidence that a flattening of
the hierarchy would not be a technical problem? Took about thirty years
for that shift in architecture of DNS to come out of the cold.

I am really referring to the scaling of DNS beyond server side hosts
which are now largely in located in data centres to satisfy the  need
for persistent identifiers for all our devices and services. That has
not happened using DNS registry business model as it has developed and
managed at ICANN. I dare say it could have happened technically. But the
business model doesn't work out to charge $10 or more per an for a
device orientated name service. The DNS has been taken over by those
using it as a pseudo business registration service. A role that the DNS
is bound to fail in satisfying.

Incidentally I am not knocking the work that Jon Postel and Paul
Mockapetris started back in 82 ish and many others have done some
amazing work on DNS which we all depend on today.  But it seems to have
gone as far as it can.

I like your use of the word "submergence" of DNS. It is a great way to
put it.

Persistence and global reach of identifiers are critical qualities for
many data applications.

DNS is continuing to serve as a naming service in the sense of being
submerged within a grander URI schema such as with Handles or other
registries.  But there is the likelihood of a different identifier model
entirely appearing.

There has been a lot of interesting work that might lead to persistent
identifier routing for data objects or graphs of semantic links to give
two examples. Both would be a move away from the "everything is a file"
Unix metaphor to address content which can lie within and across many
devices, even network boundaries.

How far the DNS as it is currently structured can usefully serve in such
an environment I don't know but it is likely to become increasingly
"submerged" as you describe and I suspect increasingly routed around.
